Abstract
A receiving apparatus 3 which is an element of a body insertable system is configured with a receiving unit 6 including receiving antennas 8a to 8d and a reception processing device 9, and a position detecting unit 7 including transmitting antennas 10a to 10d, a first linear magnetic field generator 11a, a second linear magnetic field generator 11b, a diffuse magnetic field generator 12, and a processing device 13, and the receiving unit 6 and the position detecting unit 7 are formed separately and independently of each other. Therefore, when the body insertable system is used for acquisition of intra-subject information which is acquired by the capsule endoscope 2 and position detection of the capsule endoscope 2, both the receiving unit 6 and the position detecting unit 7 are used, whereas when the body insertable system is used only for the acquisition of the intra-subject information, it is possible to use only the receiving unit 6, whereby a burden on the subject at a time of use is restricted to a minimum degree according to the purpose of use while increase in operational cost is suppressed.

8. A body insertable apparatus introduced inside a subject and acquiring intra-subject information as information concerning the subject, the body insertable apparatus comprising:
-
an intra-subject information acquiring unit that acquires the intra-subject information;
a magnetic field sensor that detects a magnetic field for position detection generated in a region where the body insertable apparatus is located;
a radio transmitting unit that transmits radio signals including at least the intra-subject information; and
a magnetic field detection controller that controls a driven state of the magnetic field sensor. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16)

17. An information acquisition method for acquiring intra-subject information concerning a subject by introducing a body insertable apparatus having functions of acquiring information inside the subject, detecting a magnetic field, and performing radio communication, the information acquisition method comprising:
-
determining whether a control signal is received or not, the control signal indicating start of detection of a magnetic field for position detection generated at a position of the body insertable apparatus;
starting a detection operation of the magnetic field for position detection when it is determined that the control signal is received in the receiving; and
acquiring the intra-subject information and detection result information of the magnetic field for position detection, and transmitting radio signals including the intra-subject information and the detection result information acquired.

18. An information acquisition method for acquiring intra-subject information concerning a subject by introducing a body insertable apparatus having functions of acquiring information inside the subject, detecting a magnetic field, and performing radio communication, the information acquisition method comprising:
-
determining whether a magnetic field for position detection is generated at a position of the body-insertable apparatus or not;
detecting the magnetic field for position detection by changing a detection period of the magnetic field for position detection to a shorter period than a predetermined reference period, when it is determined in the determining that the magnetic field for position detection is generated; and
acquiring the intra-subject information and detection result information of the magnetic field for position detection, and transmitting radio signals including the intra-subject information and the detection result information acquired.
